John, The 1107 kHz ragged-carrier mystery was noticed here last year also, and the threshold-level TP audio was almost always weak music, never with ID clues. Even after a Grayland trip last November, the 1107 mystery was unresolved. After setting up the 9' loop this month I made a serious effort to investigate who this weak 1107 music station was, and thanks to a tip from Chuck, I was able to check the KBS parallel during a music peak, to confirm the HLAV identity. Shortly thereafter, I could detect Korean-language speech on the frequency. According to Chuck, the station is never very strong, even at Grayland. Oddly, whenever HLAV has fair audio on 1107, the carrier sounds relatively clean. It seems that the ragged tone is coming from some other source, although I've never heard any co-channel TP with HLAV here (like the Japanese commercial stations you have heard). 73, Gary In a message dated 10/23/2009 11:44:31 A.M.

Gary DeBock and I have both been watching this frequency lately, in fact I've been watching it all season. Using my detailed spectrum display on the 313e (4 kHz = about 4" in a oscilloscope-type display) I can see that usually there is an on-frequency carrier there that is ragged and muddy... and the graphic spike, clean, crisp and nearly vertical with a good transmitter is all rough and it is more spread out at the base than normal. There is usually at least one well-tuned transmitter there, too. Often, that is HLAV from South Korea, but it has been one of the two or three smaller JJ commercial stations, too. Usually the two (or three?) signals combine to just produce garbage audio. However sometimes, usually near band-fade, the nasty transmitter will fade out first, or the clean signal will dominate. This same situation was going on all last Fall season, too. Does anyone have any idea who the nasty transmitter is??? Surely not Urumqi???
